The days when only big companies
got custom systems are over.
Using a separate solution each for HR, attendance, contracts and sales? Now you can build just the features you need into one system, the way your company actually works. The approval, HR and settlement records it handles accumulate as one body of company data AI can read.
FastWorks Saleser on video
Saleser handles sales within FastWorks — customers, quotes, orders and settlement flow as one, and AI reads the record.
One tool per task —
is your list of solutions still growing?
Each one is convenient, but your company's work and data end up more fragmented. The same client, the same amount, the same person gets re-entered in every service.
And the gaps in between
are mostly filled by Excel.
Quotes, pricing, settlement, status reports. In many companies, the place where most work actually gets done is still Excel.
But those solutions
weren't built just for your company.
Commercial groupware and ERP are built for many customers to share. They have plenty of features, but most of them aren't your company's work.
More features doesn't mean a better fit for your company. The ones you never use stay right there in the menus and on the screens.
Features irrelevant to your work are baked into the menus, permissions, screens — and the price.
People get lost in menus, training drags on, and it ends up a system only a few staff actually use.
Built to fit every company, the work that matters most to you is reduced to a few fields.
The rules for building custom systems have changed.
Custom systems used to be large projects demanding many people, long timelines and high costs, so they were the domain of big companies. Today, cloud, standardized development, rich APIs and reusable business modules let us deliver what companies need far faster.
| Aspect | Custom development then | Custom development now |
|---|---|---|
| Who builds | Large projects, mostly for big companies | SMEs too, starting with what they need |
| Cost | High upfront costs in the hundreds of millions of won | Reasonable cost matched to the scope of work and features |
| Timeline | Months to years to build | Core features built quickly, then improved |
| Starting scope | The whole system built at once from the start | Start with the work that matters, expand in stages |
| How it improves | Complex, rigid development procedures | Real user feedback reflected quickly |
Features you've been renting,
turned into your company's operating assets.
FastWorks doesn't ask you to replace everything at once. We move the essential features first, integrate with your existing solutions, and consolidate into your company's own system step by step.
Enter data once, and it flows into the next task.
Register an order once and the contract and owner are linked, work and delivery orders are generated, and the billing date and payment status are tracked in a single flow.
Approvals, HR and settlement records too,
as one body of data AI can read.
Records scattered across separate tools and Excel files are something AI can't read. In FastWorks, the moment sales, approvals, HR and settlement are processed, the record accumulates as one body of company data — and that data becomes the basis for AI search and analysis.
Mail and attachments are handled by MailInsight, while work records like approvals, HR and settlement are handled by FastWorks. Together, the two become the company memory AI reads.
You don't have to build a giant system from day one.
FastWorks isn't a finished product we sell. It's a service: we diagnose your company's work together and actually build the features you need.
We review your current solutions, Excel files, documents and actual workflow together.
We identify repeated data entry and subscription costs spread across multiple solutions.
We scope the work that causes the most friction and offers the biggest gains first.
We quickly build screens and processes that reflect how you already work.
We integrate with existing systems and reflect real usage feedback.
It's fine if you can't explain exactly
what kind of system you need.
No. We diagnose your work and design and build only the features you need. Every company that adopts it ends up with different screens and procedures.
No. We choose what makes sense — keep, integrate or replace. Services that work well for you are integrated and kept in use.
Yes. After checking its structure and quality, we define the migration scope. Frequently used forms are reproduced on screen as they are.
Not by user count alone. We look at feature scope, integrations, data migration and the complexity of the work together.
The team that builds your business system
builds your web presence too.
Internal systems and your public-facing web aren't separate jobs. One team handles planning, design, development and deployment, designing data and operations together.
We build business web applications your customers and partners use directly.
We take corporate sites — company profile, careers and more — from planning to operation.
We create landing pages that introduce your products and services.
We do custom development that needs to integrate with existing systems.

Show us the Excel files and processes you use today, and we'll start by mapping out what can be connected and automated.
